without the aid of any out- In the accompanying drawing:

Figure 1 is a` front elevational View ofa swing in.` accordance withmy invention; `and Figure 2 is a view taken along the line 2 2 of lFigure 1. I

`In the embodiment seiected for iuusnation, I make use of a base I upon which is mounted side frames I2 comprising beams `III converging up- I wardly andfixedly secured one to the other by Depending from the shaft I8 is a swing unit 22 A comprising abox-like enclosure 24 having a seat 26 mounted therein and a seat back 28 associated with the seat. A shaft 30 extends across the enclosure 24 vertically of the forward edge of the seat 26 and spaced equal distances from the back and front walls 32 and 34, respectively. To the shaft 30 is pivotally connected two bars 36 having their upper ends pivotally connected with the shaft I8. Straps 38 are secured to the enclosure 24 for supporting the shaft` 30.

A bracket 40 is secured to each of the bars 36 for rotatably supporting a shaft42 having a crank 44 formed therein. A gear 46 is fixed to the shaft u 42 and is arranged in rneshwithjthe gear 20.1

tofcrank 44 into movement of gear about fixed approach three hundred and sixty degrees.

Without further` elaboration, the foregoing will o so fully villustrate my invention,` that-others may,

by applying current knowledge, readily adapt the same for use under` various conditions of service.`

Iclaim: o a l. A swing comprising a supporting frame, -a

fixed gear carried at thetop of` said supporting` frame; a seat supported in the` frame below the axis of the fixed gearfbars pivotally connected with said seat and ywithsaid supporting frame coaxiallywiths'aid fixed gear, a crank rotatably carried by said bars in offset relationship thereto and having a gear meshing with said rst-mentioned gear, and bar means pivotally connected with said seat and with said crank at a point `spaced from thefirst bars.

2. Aswing comprising a supporting frame, a

shaft mounted at the top of said supporting frame and provided with a fixed gear, a. seat supported onthe frame below the axis of the xedgear, bars pivotally connected `with said seat and with said shaft, a crank rotatably carried by said bars in To the crank 44 is pivotally connected two bars y 48, each pivotally connected at its lower end with a shaft `5I! adjacent the sides 52 of the enclosure 24 and closely adjacent the front wallr34. Plates 54 are secured t0 the enclosure 24 for supporting the shaft 50, the latter lying in parallelism with theshaft 3U. Shaft 42 lies in `parallelism with the shaft I8 and the gear 20 is coaxial with the shaft I8.

`offset relationship thereto and having a gear meshing with said nrstfm'entioned gear, `and bars pivotally connected with said seat and withsaid crank at a point spaced from the first bars.

`3. A swing comprising a base having spaced up;

right supports, a shaft carried by the upper ends `ofsaid supports and having a fixed gear coaxially l of-said bars, brackets mounted on said hars,"a

In operation, a person enters the box-like swing enclosure 24 of swing unit 22 and occupies the seat 26 and upon leaning back and forth sets the swing initially in motion by shift of `weight which in turn is translated through bars 48 connected` `crank rotatably journaled in said brackets and having a gear meshing with said fixed gear, and upright second bars pivotally connected at their upper ends with said crank shaftand at their lower ends with said seat'laterally of said flrstmentioned bars.
